Martin "Marty" Bergen (October 25, 1871 - January 19, 1900) was an AmericanMajor League Baseball player from 1896 to 1899. He played in 344 games during his four-year career with the Boston Beaneaters, 337 of them as their catcher. Bergen helped the Beaneaters win two straight National League pennants (1897 and 1898), as well as a second-place finish in 1899.

He was considered a superior defensive catcher, as compared to his contemporaries. A 2001 article about him described him as "a nimble fielder with a bullwhip arm who could snap the ball to second base without so much as moving his feet".

Bergen's career and life ended suddenly, when he killed his wife and two children, then took his own life. Despite this, he received one vote in both 1938 and 1939 to enter the Baseball Hall of Fame.
